Problems solved by technology

[0008] However, from figure 1 It can be seen that if the porous material n is not filled up to 100% in the resonance space during the filling of the porous material, the porous material n may collide with each other and collide with the upper case 11, the lower case 12 and the cover 14 or the micro Loudspeaker A collides, creating noise

Embodiment Construction

[0031] Hereinafter, preferred embodiments of a micro speaker cabinet having a porous material in a resonance space according to the present invention will be described in detail with reference to the accompanying drawings.

[0032] figure 2 A microspeaker enclosure with a porous material according to a first embodiment of the present invention is illustrated.

[0033] The microspeaker cabinet with porous material according to the first embodiment of the present invention includes: a microspeaker A; a cabinet 100 containing the microspeaker A, the cabinet defines a resonance space R and has an upper casing 110 and a lower casing 120 ; and a porous material n filled in the resonance space R of the box body 100 . In addition, support members 210 and 220 are disposed between the upper case 110 and the micro speaker A and between the lower case 120 and the micro speaker A to support the micro speaker A, respectively. Here, a filling hole 130 through which a porous material n is ...

Abstract

The present invention discloses a microspeaker enclosure with porous materials, including a microspeaker, an enclosure with the microspeaker therein, the enclosure defining a resonance space and having an upper casing and a lower casing, porous materials filled in the resonance space of the enclosure, and an anti-noise structure which prevents at least one of a collision between the porous materials, a collision between the porous materials and the enclosure, a collision between the porous materials and the microspeaker, and introduction of the porous materials into the microspeaker.

Description

technical field [0001] The present invention relates to a microspeaker enclosure with a porous material in a resonance space for increasing low frequency sound pressure level (SPL) and reducing low frequency total harmonic distortion (THD). Background technique [0002] Microspeakers are installed in portable devices and the like to generate sound. With the recent development of mobile devices, micro speakers have been installed in various mobile devices. In particular, the latest mobile devices tend to have light weight, small size, and slim shape for portability, and therefore, microspeakers mounted in mobile devices are required to have small size and slim shape. [0003] However, in the case of a microspeaker having a small size and an elongated shape, the area of ​​the diaphragm (diaphragm) is reduced, and the volume of the resonance space that resonates and amplifies the sound generated by the vibration of the diaphragm is also reduced, so the acoustic The pressure l...
